Title: Electroformed thick-walled perforated sleeve - with mould release aided by inducing internal stresses
Inventor: DUCHENAUD ALAIN
IPC: C25D1/02
Filed: 1978-03-02
Abstract: A thick-walled perforated cylindrical sleeve is mfd. by electrodeposition. A die is sensitised by deposition of a photosensitive layer and a pattern is copied on to this resin which is subsequently developed. Electrodeposition is then carried out. The contour and the density of the pattern points, the thickness and the treatment of the photosensitive resin, and the deposition conditions are studied as a function of the desired thickness without significantly deforming the pattern points and hence the perforations. The mould is removed using internal stresses b uilt up in the deposited metal, these stresses being controlled throughout the deposition in a range with a maximum at which peeling occurs during deposition and with a minimum at which removal from the mould is not possible without plastic defomation taking place and deterioration of the sleeve. The roll or sleeve can be used to impart a relief or cover with a protective varnish a design previously printed in several colours.
Patent DE-2815011-A1 (DE)
Title: Seal for melting pot for aluminium under vacuum - consists of elastic tube and ring in flange of cover
IPC: F27D99/00
Filed: 1978-04-07
Abstract: Between a circumferential zone of the cover which fits coaxially over or into a vessel for the melting under vacuum of metals, and a circumferential zone of the vessel, there is a heat resisting, elastic, tubular body. This can be inflated so as to act against one surface of a flat elastic element, which lies against its outer or inner circumference. The tube, at least on its outer surface and the elastic ring enclosing it are of good sealing material. The two fit in a "U"-flange with the elastic ring against the surface of the vessel. The seal can be made more easily and quickly after a charge has been put in or a load withdrawn, and remains good irrespective of changes in temp. The operator needs only to put the tube under pressure.

Title: Automatic switching of two sound sources - uses electronic switch and first source is normally connected, while second source is connected when it delivers signal
Inventor: BENCINI ROBERTO
IPC: H04H60/04
Filed: 1978-07-05
Abstract: In its rest state the switch (K) connects the first signal source (To) to an amplifier, and in its operated state it connects the second signal (TM) source to the amplifier. A sensor for signal detection is permanently connected to the second signal source, and operates the switch when the second source delivers a useful signal.

Title: Steam-cracking of heavy hydrocarbon(s) - using the waste heat to pre-heat the oil before and after previous hydrogenation
Inventor: KREUTER WALTER DR
IPC: C10G69/06
Filed: 1978-07-13
Abstract: Cracking of hydrocarbons is in presence of steam after previous catalytic hydrogenation, in which waste heat arising from cracking is used to pre-heat the feed to, and liquid product from, hydrogenation. Method is used for prodn. of olefins from oil fractions boiling at over 200 degrees C, e.g. gas oil or vacuum gas oil. Waste heat from the cracking process is fully utilised, avoiding the need for utilisation in another process and associated costs and heat losses. Preheating is carried out in several stages, using: waste heat at various temp. levels. That at its highest temp. is pref. used to heat the liquid hydrogenation product. Preheating of the feed before hydrogenation is carried out by heat exchange with the combustion gas from a tubular cracking furnace heated by burners. Hydrogenation is pref. at higher pressure than cracking, the liquid product being released through an ejector, to which the steam used in cracking is added. The gas phase after hydrogenation is pref. recycled to the feed.

Title: Solar energy powered irrigation pump - has membrane pump operated by vapour produced in solar energy collector and exhausting to condensate pump
Inventor: AMANAT SCHAHRYAR DIPL ING
IPC: F04B43/06
Filed: 1978-09-28
Abstract: An organic liquid is contained in a reservoir from which it flows to a solar energy collector. It is evaporated and the vapour flows through a liquid separator to the driving side of a double acting membrane pump. The pump raises water for irrigation from a suction connection through a condenser to a discharge connection.
